Bangkok:The Royal Irrigation Department has stated that the release of water from the Pa Sak Dam is being managed gradually and according to current conditions, ensuring no adverse effects on Bangkok.

According to Thai News Agency, the dam is releasing water at a rate of 400 cubic meters per second to maintain safety and appropriate water levels, following heavy rainfall in the upper Pa Sak River basin. The dam is currently at full capacity, holding 962 million cubic meters as of early October 2026. Adjustments to the release rate will be made based on inflow and rainfall patterns, with inflow levels currently decreasing, suggesting a return to normalcy for the river basin soon. The reservoir's full capacity also secures adequate water reserves for the upcoming dry season.

The released water will travel to the Rama VI Dam, which is discharging at 546 cubic meters per second, causing the water level downstream in the Pasak River to rise by about 1.00-1.20 meters. The flow will then merge with the Chao Phraya River, reaching Pathum Thani Province at a rate of roughly 2,444 cubic meters per second. The flow will be controlled to not exceed 3,600 cubic meters per second to avoid impacting Bangkok, with considerations for local rainfall and tidal conditions affecting drainage into the sea. The Royal Irrigation Department will continue to monitor the situation closely to manage water volume effectively and minimize any public impact.
